[摘要]：In the present paper, highly efficient organic optoelectronic conversion has been demonstrated, induced by the electric double layers (EDLs) in ionic liquids. For the organic photocell, indium tin oxide/ionic liquid/charge-separation layer (zinc phthalocyanine:fullerene)/aluminum, in which the EDLs enhance the charge separation, a large photocurrent response can be generated. By this method, the internal quantum efficiency can reach 93% and a responsivity of 142 mA/W can be achieved. Since the EDLs show little dependence on the thickness of the ionic liquid, a very large photocurrent can be produced without the electrodes being superimposed along the light path.
